I read a blog called Worm Spit, sponsored and authored by a gent whose passion is silkworms, silk, and everything in between. Lately, his camera and his interest has been focused on his gorgeous garden and all of the flora and fauna thereof.
One of the latest posts is something that you can share with the children, and they just might get it. "Charlotte Changes"
shows a spider who shed her skin, and then built herself a new web, too.
The whole web site is at Wormspit.com
. I recommend it. He has a great perspective on life, and excellent photos to go along with it. From bees to baby squash to chickens (FREEBIRD!), it's a fun look at urban farming.
